Acetic acid is an important chemical feedstock. The electrocatalytic synthesis of acetic from CO2 offers a low-carbon alternative to traditional synthetic routes, but the direct reduction comes with crossover energy penalty. CO electroreduction bypasses this, which motivates interest in cascade approach followed by acid. Here we report catalyst design strategy off-target intermediates (such as ...

In the present study, a simple, efficient and fast synthetic strategy was reported for the green biosynthesis of silver nanostructures (i.e. nanoroads and nanoparticles) by the extract of Suaeda Acuminata plant, without any catalyst, template or surfactant. Aqueous extracts were obtained by maceration and microwave assisted extraction (MAE) methods. In MAE procedure, the effec...

Cerium nanopowders doped by a small amount of silver exhibit interesting catalytic properties towards the low temperature oxidation of CO. It is generally believed that a metal support interaction plays an important role in a catalytic process. Therefore in our study we examined electronic and adsorption properties of cerium deposited onto a polycrystalline silver substrate. Layers of approxima...

Sol-gel method has been used to fabricate nanocomposite films on glass substrates composed halloysite clay mineral and nanocrystalline TiO2. The methodology for the synthesis involves a simple chemistry method utilized nonionic surfactant molecule as pore directing agent along with the acetic acid-based solgel route with the absence of water molecules. The thermal treatment of composite films a...

Computational chemistry has shown that backbone-alkylated imidazoles ought to be efficient ligands for transition metal catalysts with improved carbene-to-metal donation. In this work, such alkylated imidazoles were synthesized and complexed with silver(I) by means of an eight/nine-step synthetic pathway we devised to access a new class of biologically active silver complexes. The synthesis inv...

Lowering the overpotential for the electrochemical conversion of CO2 to useful products is one of the grand challenges in the Department Of Energy report, “Catalysis for Energy”. In a previous paper, we showed that CO2 conversion occurs at low overpotential on a 1-ethyl-3methylimidazolium tetrafluoroborate (EMIM-BF4)-coated silver catalyst in an aqueous solution of EMIM-BF4. One of the surprise...

Silver nanoparticles-anchored reduced graphene oxide (Ag-RGO) is prepared by simultaneous reduction of graphene oxide and Ag(+) ions in an aqueous medium by ethylene glycol as the reducing agent. Ag particles of average size of 4.7 nm were uniformly distributed on the RGO sheets. Oxygen reduction reaction (ORR) is studied on Ag-RGO catalyst in both aqueous and non-aqueous electrolytes by using ...

In this paper metal-assisted chemical etching has been applied to pattern porous silicon regions and silicon nanohole arrays in submicron period simply by using positive photoresist as a mask layer. In order to define silicon nanostructures, Metal-assisted chemical etching (MaCE) was carried out with silver catalyst. Provided solution (or materiel) in combination with laser interference lithogr...
